Hi,

I am planning to use the TC1174 to regulate a 5V down to 3.6V. Please see the attached schematic.

Vin = 5V and max. 500mA can ne drawn from this Vin.

Vout = 3.6V and max 300mA (TC1174's max current output) can be drawn from Vout.

The max power (worst case) out is:

Pout = VI = 3.6V * 300mA = 3.6 * 0.3 = 1.08W

Note that I will adjust R2 accordingly to get a Vout = 3.6V.

My question is: Is 1/2W resistor rating for R1 and R2 enough, since there is current divider going through the Vout and the resistors?

Thanks
